Such as shown in Figure 6A, in the manufacturing method of electrochemical device electrode of the invention, so that negative electrode collector The increased mode of reactivity of 132 interarea 132s carries out the processing of interarea 132s.Such as the interarea to negative electrode collector 132 132s carries out ultraviolet light irradiation, Corona discharge Treatment, plasma irradiating (atmosphere plasma, reduced pressure plasma etc.) and electricity The arbitrary processing 132tr (ST01) of beamlet irradiation, ion beam irradiation etc..132tr through this process, negative electrode collector 132 Interarea 132s becomes activity.For example, the combination of aluminium and oxygen is cut off or aluminium is negative in the interarea 132s of negative electrode collector 132 At least part of electrode current collector 132 is exposed.
In addition, organic solvent, lotion etc. can be used by cathode collection before implementing processing 132tr to negative electrode collector 132 Electric body 132 is cleaned.Dust, grease of negative electrode collector 132 etc. is attached to as a result, to be removed before implementing to handle 132tr.
Then, as shown in Figure 6B, make the interarea 132s (ST02) of alkaline solution contact negative electrode collector 132.The alkalinity is molten Liquid includes organic matter.Organic matter is for example comprising carboxyl.The contact of alkaline solution for example carries out in an atmosphere.The contact of alkaline solution It can be carried out, negative electrode collector 132 can also be soaked by the way that alkaline solution to be sprayed to the interarea 132s of negative electrode collector 132 Enter alkaline solution.
By making alkaline solution contact negative electrode collector 132, such as oxygen, hydrogen-based and negative electrode collector in alkaline solution Reactive aluminum in 132 forms cathode al oxide layer 135 in the interarea 132s of negative electrode collector 132.Fig. 6 C indicates the state.
Cathode al oxide layer 135 is, for example, cellular.Cathode al oxide layer 135 includes aluminium hydroxide and aluminium oxide.

Then, as shown in Figure 7 A, conductive material is applied in the interarea 135s of cathode al oxide layer 135, makes the conduction Property material it is dry (ST03).The coating of conductive material for example carries out in an atmosphere.As a result, in cathode al oxide layer 135 Interarea 135s forms negative conducting layer 136.A part of 136p of negative conducting layer 136 enters opening 135h, negative conducting layer 136 A part of 136p directly contacted with negative electrode collector 132.In addition it is also possible to use the conductive material of alkalinity.
The material high with the compatibility of aluminium hydroxide and aluminium oxide can be selected as conductive material.Such as conduction Property material is able to use the water system liquid for being dispersed with conductive material.Conduction material is, for example, at least one of carbon black, graphite etc..
Then, as shown in Figure 7 B, negative electrode active material layer 133 is formed in the interarea 136s of negative conducting layer 136 (ST04).Manufacturing process (ST01~ST04) in this way forms cathode 130.
[effect of cathode and anode]
In cathode 130 of the invention, cathode al oxide layer 135 is formed on negative electrode collector 132.Cathode alumina Nitride layer 135 includes aluminium hydroxide and aluminium oxide.Cathode al oxide layer 135 is cellular.
The cathode al oxide layer 135 is formed under alkaline condition (for example, pH8.0 or more).As a result, in negative electrode collector The cathode al oxide layer 135 comprising aluminium hydroxide and aluminium oxide is stably formed on 132.Here, oxygen (O) in aluminium oxide and Hydroxy (OH) in aluminium hydroxide is combined strongly with the aluminium (Al) in negative electrode collector 132.Cathode al oxide layer as a result, 135 and negative electrode collector 132 be close to (contiguity) strongly.Cathode al oxide layer 135 in multiple batch processings every time steadily It is formed on negative electrode collector 132.
In addition, the film thickness and self-souring film of cathode al oxide layer 135 are thicker in cathode 130 of the invention (for example, 2 μm of 1nm or more or less).Also, a part of 136p of negative conducting layer 136 is via cathode al oxide layer 135 and bears Electrode current collector 132 directly contacts.Pass through the anchoring effect of cathode al oxide layer 135 (anchor effect, fixed effect as a result, Fruit), negative conducting layer 136 and cathode al oxide layer 135 are close to strongly.
In addition, negative conducting layer 136 passes through the water system liquid for making to be dispersed with conductive material coated in cathode al oxide layer 135 and be formed on cathode al oxide layer 135.Here, water system liquid and the compatibility of aluminium hydroxide and aluminium oxide are good.By This, interarea 135s and be open 135h in efficiently infiltration spread of the water system liquid in cathode al oxide layer 135.
Negative conducting layer 136 after making water system liquid dry as a result, and the contact area of cathode al oxide layer 135 are reliable Ground increases.That is, in the present invention, other than anchoring effect, using chemical affinity, improving negative conducting layer 136 and cathode The clinging force of al oxide layer 135.
Also, a part of 136p of negative conducting layer 136 is straight via cathode al oxide layer 135 and negative electrode collector 132 Contact.The resistance between negative conducting layer 136 and cathode al oxide layer 135 reduces as a result,.As a result, being formed in Its resistance also reduces between negative electrode active material layer 133 in negative conducting layer 136 and negative electrode collector 132.
As described above, cathode 130 according to the present invention, is formed between negative conducting layer 136 and negative electrode collector 132 Cathode al oxide layer 135.The resistance between negative electrode active material layer 133 and negative electrode collector 132 reduces as a result,.
In addition, the construction of anode 140 is identical as cathode 130, anode 140 can also obtain effect identical with cathode 130.
In addition, have and above-mentioned processing 132tr is not carried out to negative electrode collector 132 as comparative example, and in negative electrode collector The method of negative conducting layer 136 is directly formed on 132.In this case, because being formed in the interarea 132s of negative electrode collector 132 Self-souring film (Al2O3) presence, the wellability of negative conducting layer 136 deteriorates.
Another party has after having carried out corona discharge to the interarea 132s of negative electrode collector 132, makes as another comparative example Interarea 132s is exposed to the method for water.But in the method, due to manufacturing environment, water becomes acid or alkalinity, has Possible aluminium hydroxide cannot stably form on negative electrode collector 132.In addition, by exposing negative electrode collector 132 again to the open air Yu Shui, the case where the one side of negative electrode collector 132 forms aluminium oxide.In this case, in the same manner as above-mentioned comparative example, cathode The wellability of conductive layer 136 cannot become good.
